Title: Critical bug in v1.3 that intervenes in EACH request in admin panel Last modified: October 26, 2025 --- # Critical bug in v1.3 that intervenes in EACH request in admin panel * [daiohansed](https://wordpress.org/support/users/daiohansed/) * (@daiohansed) * [5 months, 2 weeks ago](https://wordpress.org/support/topic/critical-bug-in-v1-3-that-intervenes-in-each-request-in-admin-panel/) * We noticed that random plugins stopped saving changes to their settings — no error, the page just normally reloads after submitting the form yet no changes are applied. Then we noticed that even certain basic actions, such as deleting or updating plugins, stopped working — the XHR request to admin-ajax.php returned 400 Bad Request with “0” in response. * After deactivating plugins one by one, we’ve pinpointed the issue to your plugin. Then we’ve found out the exact piece of code that causes it: [https://share.cleanshot.com/6PxwyysfRm1nZxKtq2KL](https://share.cleanshot.com/6PxwyysfRm1nZxKtq2KL). In v1.3, you started calling plugin_options() on ‘init’ instead of ‘after_setup_theme’. And inside one of the CSF::_createSection_(), that method calls $this->getPaymentOptions() on line 114. This is the method that breaks everything. * We didn’t dig further, so the only possible explanation we have is from AI: * > $this->getPaymentOptions() invokes WC()->payment_gateways->payment_gateways(), > forcing early initialization of all WooCommerce payment gateway classes in > an AJAX context. > Gateway initialization can trigger side effects: loading files, > registering hooks, emitting notices or accidental output (echo). Any unexpected > output before the AJAX handler finishes corrupts the expected response format. > When the AJAX response is polluted or interrupted, WordPress falls back to > returning 0 or a 400 Bad Request. * P.S. no, we’re not able to provide you with a sandbox website to experience it yourselves. But I hope that’s enough.
